I've never even heard or seen these until today browsing through youtube.
I think I might buy one, not necessarily a current one, but just for the sake of having one and looking through it.
In fact, you know what, I just might buy a current one, since I don't even know all the Gen IV and Gen V pokemon yet, and haven't fully played through these (yet).

Anyway, what do you guys think of these?
Waste of money? Memorabilia? Useful?
